Platers/Painters Profile: Metal Finishing—C.R. Hudgins Style Platers/Painters Profile: Metal Finishing—C.R. Hudgins Style

Investing in the business—and its people—pays big dividends for C.R. Hudgins Plating, a 60-year-old operation based in Lynchburg, Va.

Performance Characteristics of Zinc–Nickel Alloys and Dip-Spin Coatings Performance Characteristics of Zinc–Nickel Alloys and Dip-Spin Coatings

As the performance criteria for plated components have become more demanding, directives to meet strict environmental considerations have forced sweeping changes to surface finishes. The resulting field performance has been as varied as the alternatives. This article will compare zinc–nickel alloy plating and dip-spin coating technology with regard to various critical performance characteristics for automotive component applications. Corrosion resistance, total friction co-efficient, and contact with dissimilar metals, among other key properties, will be discussed.

Trivalent Passivates Need Trivalent Post-Dips Trivalent Passivates Need Trivalent Post-Dips

Atotech's Björn Dingwerth discusses the benefits of an environmentally friendly trivalent chromium-based post-dip. This post-dip helps reinforce trivalent chromium-based conversion coatings while also preserving decorative appearance and corrosion protection properties.

Zincate- or Stannate-free Plating of Magnesium, Aluminum, and Titanium Zincate- or Stannate-free Plating of Magnesium, Aluminum, and Titanium

For more than 80 years, the plating industry has been dependent on the use of various zincate and/or stannate solutions to assist in the plating of metals such as titanium, aluminum, and magnesium. It is becoming ever more difficult to use these solutions due to restrictive regulations—plus, they are difficult to work with. This article presents an environmentally acceptable and easy-to-work-with alternative process that does not require the metalizing of the metals to be plated or extensive cleaning and deoxidization procedures.
